I would compare Felicity to the Flash in the Justice League animated series: sees everything as a game up until "things get serious" on a personal level. Felicity's last Exhibition performance and her rough treatment with the cattle prod, and thus the loss of her playmate, has pushed her past her naivete. To go forward now without quitting, she either has to double-down on her self-delusion that "it's all fun and games", or "alright, this is more than I bargained for, but momma didn't raise no quitter". Considering she feels betrayed by Edwin, I'm guessing the latter, but she might throw a "happy-go-lucky" facade to the club audience, even though everyone on-stage knows about her perspective change, thinking that's her best play to keep the patrons' interest in her come the final vote.
